1. Chapter 7 & 8
Bones & Joints

2. Long bone structures

3. Bone Parts

4. Bone types Long – arm, finger; red and yellow marrow
All others have red only
Short – wrist, ankle
Flat – scapula, cranial
Irregular – vertebrae

5. Osteon

6. Building/Maintaining bone
Intramembranous Ossification
Endochondral Ossification

7. Fetal Skull

8. Maintenance - Osteoclast

9. Maintenance - Osteoblast

10. Spongy bone - trabeculae
Normal trabeculae
Osteoporosis trabeculae

11. Bone break classification
Open vs. closed
Complete vs. incomplete
Displaced vs. nondisplaced

12. Incomplete - Greenstick fracture

13. Complete - Comminuted fracture

14. Complete - Comminuted

15. Linear - Incomplete

16. Complete, transverse, displaced

17. Complete, transverse, displaced

18. Complete, transverse, displaced

19. Complete, oblique, displaced

20. Complete - Spiral fracture

21. Colles’ fracture

22. Potts’ Fracture

23. Avulsion
Torn off!

24. Bone Healing

25. Bone Disorders

26. Osteoporosis
Normal trabeculae
Osteoporosis trabeculae

27. Osteomalacia (Rickets)

28. Paget’s Disease
Paget’s x-ray
Normal x-ray
trabeculae

29. Histiocytosis

30. Osteomyelitis

31. Joint Classification Structural Fibrous – fibers connect
Suture
Gomphosis
Syndesmosis
Cartilaginous – special cartilage connects
Synchondrosis - yellow
Symphysis - blue
Synovial – cartilage, fluid (sprain)
Monaxial
Biaxial
Multiaxial

32. Suture (fibrous)

33. Gomphosis (fibrous)

34. Syndesmosis (fibrous)

35. Synchondrosis (cartilaginous)

36. Symphysis (cartilaginous)

37. Synovial (diarthritic)

38. Synovial types
Uniaxial Biaxial Multiaxial

39. Joint Classification Functional – EASY! S.A.D.
Synarthrosis – no movement
Amphiarthrosis – somewhat moving
Diarthrosis – freely moving

40. Joint Disorders sprain – stretched/torn ligament
cartilage – won’t repair
dislocation
bursitis – inflammation of synovial joint
tendonitis – swelling of tendon
arthritis – swelling of joints
osteoarthritis – bone erosion; common
rheumatoid – immune system attacks cartilage; women 3X more than men
gouty – uric acid deposits in joints, bones fuse; women > men

41. Osteoarthritis

42. Rheumatoid Arthritis

43. Gouty Arthritis

44. Review Time! Description of osteon structures
Classify bone breaks from description
Classify joint from description
Structural AND/OR functional
Describe 2 types of bone growth
Diagram and discuss parts of osteon
Label long bone structures
Discuss different bone & joint disorders
Lab practical:
